Hermes Agent: The Architecture Behind Real AI Agents

Hermes Agent is not just an AI chat wrapper. It is a durable agent runtime: one loop, one internal message format, one tool registry, one persistent session store, and a set of extension surfaces around that core. Source: https://github.com/NousResearch/herme... This walkthrough focuses on the implementation layers you would need to replicate: the architecture map (https://hermes-agent.nousresearch.com..., the agent loop (https://hermes-agent.nousresearch.com..., provider adapters (https://hermes-agent.nousresearch.com..., tool dispatch (https://hermes-agent.nousresearch.com..., terminal backends (https://hermes-agent.nousresearch.com..., security gates (https://hermes-agent.nousresearch.com..., SQLite sessions (https://hermes-agent.nousresearch.com..., compression (https://hermes-agent.nousresearch.com..., memory (https://hermes-agent.nousresearch.com..., skills (https://hermes-agent.nousresearch.com..., hooks (https://hermes-agent.nousresearch.com..., subagents, gateway routing, cron, dashboard surfaces, and the practical rebuild order. Built from public docs, papers, talks, and code, then vetted by senior software engineers for correctness, tradeoffs, and real-world failure modes.
